Issue #7883 has been updated by charliesome (Charlie Somerville).
> You can use /\Ab/.method(:=~).
This is more typing than just using '{ |x| x =~ /\Ab/ }'.
I like this idea, it's something I have to do quite often.

Feature #7883: Add Regex#to_proc
https://bugs.ruby-lang.org/issues/7883#change-36602
Author: rklemme (Robert Klemme)
Status: Open
Priority: Normal
Assignee:
Category: core
Target version: 1.9.3
Just a small addition to the standard library:
class Regexp
def to_proc; lambda {|s| self =~ s} end
end
With that one can use a Regex everywhere a Proc is used as filtering criteria saving a bit of typing. While we have Enumerable#grep already there may be other cases where you want to do something like
irb(main):008:0> %w{foo bar baz}.select &/\Ab/
=> ["bar", "baz"]
irb(main):009:0> %w{foo bar baz}.reject &/\Ab/
=> ["foo"]
irb(main):010:0> %w{foo bar baz}.find &/\Ab/
=> "bar"
Note: line 9 and 10 are not possible with Enumerable#grep AFAIK.
I see low risk of breaking something.
